Well, it came yesterday. Great box. Looks like the challenge will be
'mounting' the GXM 30 XM antenna in the Maule.

The thing has a big non-removeable magnet so distance from the compass
is needed. It has an extension cord and mounting screws but needs good
sky exposure... any thoughts are welcome.

Otherwise, the yoke mount looks fine and the unit itself has me
drooling. NC to FL next week!
